Embodiments of the invention relate to an improved grip for use with thehandle portion of articles, in particular, the handle portion of fishingpoles and golf clubs. Embodiments of the invention also relate toarticles having an exchangeable handle, particularly in the context offishing poles.

Description of the Related Art

Though grips have been developed, there remains a need for an improvedgrip. In addition, though handles have been developed there remains aneed for an efficient way to exchange handles particularly handleshaving a gripping portion.

SUMMARY OF THE INVENTION

Some embodiments provide a grip that is light in weight and reduces oreliminates the absorption of water. Some embodiments provide a feelingof tackiness while also minimizing the weight/density of the grip.Embodiments can be configured for use with at least a portion of thehandle portion of a variety of articles including fishing poles and golfclubs. Some embodiments include an ethylene-vinyl-acetate (EVA) base orunderlisting and a gripping portion including an EVA inner or backinglayer. In some embodiments, the gripping portion can include acombination polyurethane and thin fabric layer that is joined to the EVAinner layer. The fabric layer can be impregnated with polyurethane. Insome embodiments, the polyurethane further includes a woven fabric meshlayer disposed outside the impregnated fabric layer.

Some embodiments provide a method of manufacturing a grip use with atleast a portion of the handle portion of a variety of articles includingfishing poles and golf clubs. In some embodiments, the method includesgrinding an underlisting sleeve from a block of foam EVA. In someembodiments, the method includes injection molding an EVA underlistingsleeve. In some embodiments, the method further includes dipping a thinfabric substrate into a bath of polyurethane so as to coat both sides ofthe fabric substrate with polyurethane and to allow polyurethane to soakinto and permeate through the fabric substrate, removing a substantialportion of the polyurethane from one side of the fabric substrate andsmoothing the outer surface of the polyurethane on the other side of thefabric substrate. The method may further include dipping thepolyurethane soaked fabric substrate into a water bath to facilitate thecoagulation of the polyurethane in and around the fabric substrate. Thecoagulated combination substrate of polyurethane and thin fabric can besqueezed, by for example, by a pair of rollers, to squeeze fluid fromthe coagulated polyurethane pores.

Some embodiments provide a grip configured for use with a handle portionof an article, wherein the grip includes a sleeve member and a grippingmember. In some embodiments, the sleeve member comprises ethylene vinylacetate, includes a hollow cavity configured to receive at least aportion of a handle portion of an article, and defines a first end, asecond end and a mounting surface. In some embodiments, the grippingmember is joined to the sleeve member and comprises an inner layercomprising ethylene vinyl acetate and an outer layer comprising a firstfabric and polyurethane wherein the first fabric is thin relative to thepolyurethane to facilitate penetration of the polyurethane through thefabric from an outer surface of the fabric to an inner surface of thefabric. In some embodiments, the polyurethane and first fabric cooperateto define an inner surface for the outer layer, the inner surface of theouter layer being joined to an outer surface of the inner layer of thegripping member, wherein the inner layer of the gripping member isjoined to the mounting surface of the sleeve member such that theethylene vinyl acetate sleeve member is joined to the ethylene vinylacetate gripping member.

Some embodiments provide a method of making a grip for use with thehandle portion of an article comprising the steps of providing a sleevemember comprising a hollow cavity configured to receive at least aportion of a handle portion of an article, the sleeve member comprisingethylene vinyl acetate and defining a first end, a second end and amounting surface. In some embodiments, the method further includesdipping a first fabric sheet comprising an inner surface and an outersurface into liquid polyurethane such that polyurethane coats both theinner surface and the outer surface and penetrates through the firstfabric sheet between the inner and outer surfaces and joining the dippedsheet to the mounting surface of the sleeve member.

Some embodiments provide a gripping material configured for use with thehandle portion of an article, the gripping material an inner layercomprising ethylene vinyl acetate and an outer layer. In someembodiments, the outer layer includes an inner surface and an outersurface and comprises a thin fabric member having an inner surface andan outer surface defining a substantially uniform fabric thicknesstherebetween. In some embodiments, the fabric member is substantiallyimpregnated by polyurethane such that the polyurethane penetratesthrough the fabric member to form, in combination with at least aportion of the fabric member, the inner surface of the outer layer. Insome embodiments, the polyurethane in the outer layer defines at least aportion of the outer surface of the outer layer and defines apolyurethane thickness extending from the outer surface of the fabricmember to the outer surface of the outer layer, wherein the polyurethanethickness and the fabric thickness defining a thickness ratio ofapproximately 1. In some embodiment, the outer layer is adhered to theinner layer.

Embodiments of the present invention include one or more advantagesincluding offering great feel by transmitting sensitive vibrations tothe hand of a user and being light in weight and of low density. In thecontext of fishing pole grips, the low density and extremely lightweight allows the grip to float in water regardless of how wet itbecomes. In the context of golf club grips, lighter grips allow for themanipulation of the club swing weight. Current common grips weighapproximately 52 grams. Embodiments of the present invention can reducethe weight of the grip by approximately 32 grams. Generally, decreasingthe weight of a grip by approximately 4.5 grams will increase one unitof the club's swing weight. Thus, a 32 gram savings in grip weight canincrease a club's swing weight by approximately 7 units. Increased swingweight allows a golfer to hit the ball further with a similar stroke.Further, decreasing the weight of a grip will decrease the total weightof a club, feature that can be beneficial to older and female golfers.Furthermore, light weight grips are important for longer shafted clubswhich may be preferred by longer distance and taller golfers. Inaddition, a golfer generally carries approximately 14 clubs in theirbag. When that golfer is walking the course or carrying the bag anyappreciable distance, it is advantageous to reduce the weight of the bagas much as possible. This can be accomplished by using embodiments ofthe present grip that are much lighter than standard grips.

An aspect of at least one of the embodiments disclosed herein includesthe realization that the handles on articles can require exchange orreplacement. Sometimes, the handles can have gripping portions that canbecome damaged or worn, often due to repeated use. In the context offishing pole grips, the wet environments and the exposure to outdoorconditions can expedite the deterioration of the handle and grips.

Thus, in accordance with at least one of the embodiments disclosedherein, a handle can be configured for use with at least a portion of afishing pole. The handle can comprise a grip portion comprising a cavityopen to at least one end, the cavity extending longitudinally at leastpartially through the grip portion. A shaft can have a first end and asecond end with the first end of the shaft at least partially insertedinto an open end of the grip portion. Coupled to the second end of theshaft can be an adapter comprising a first coupling member. The adaptercan be configured to be releasably attached to a second coupling memberon a rod portion.

Some embodiments can include a handle comprising a grip portion, a shaftextending from the grip portion, and a first coupling member disposed onat least a portion of the shaft. The first coupling member can beconfigured to be releasably attached to a complimentary second couplingmember disposed on an article.

In a method of using a fishing pole with an exchangeable handle, themethod can comprise the steps of unbinding the exchangeable handle fromthe fishing pole and removing the exchangeable handle from the fishingpole. Once the exchangeable handle is removed, another exchangeablehandle can be introduced to the fishing pole and bound to the fishingpole.

Embodiments can provide the ability to customize an article fordifferent situations by easily exchanging a handle of the article. Inthe context of fishing pole, the handle can be exchanged for a handlewith a gripping portion that is better suitable for a specificsituation, such as to accommodate for different weather conditions, sizeand type of fish, or user's preferences.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 is a perspective view of a fishing pole FP incorporating a grip Gaccording to some embodiments.

FIG. 2 is a front view of an underlisting sleeve member 2 or sleeveaccording to some embodiments. The sleeve 2 includes a cavity 4configured to receive at least a portion of the handle portion of afishing pole or other article. In some embodiments, the sleeve 2 furtherincludes a first end 6 with an opening 10 (FIG. 30 ) adapted to receivethe handle portion and a second end 8 including a substantially enclosedclosed end. A mounting surface 12 or body extends between the first andsecond ends 6, 8.

In some embodiments, the first end 6 may include a nipple 14, which insome embodiments is a stepped structure configured to accommodate afinger hook 15 of a fishing rod FP. Alternatively, in some embodimentsthe nipple 14 may be tapered to provide a smoother transition from thesmaller diameter exposed handle, rod, or shaft near the nipple to themain gripping portion of the grip G. The nipple 14 may be integrallyformed with the mounting surface 12 or may be separately formed andlater joined to the mounting surface 12. In some embodiments, the nipple14 may define a circumferential nipple ledge 16 extending around thesleeve member 2 and extending radially outward from the mounting surface12 of the sleeve member 2 adjacent the mounting surface 12. The nippleledge 16 may comprise a nipple contact surface 18 and a nipple outersurface 20.

In some embodiments, the second end 8 may include a cap structure 22.The cap 22 may include an opening 24 to facilitate the escape of air asa handle is inserted into the sleeve 2 or to facilitate the escape ofmoisture from the handle or other part of the fishing pole. The cap 22may define a generally convex shape on its end. In some embodiments, thecap 22 defines a circumferential cap ledge 26 extending around thesleeve member 2 and extending radially outward from the mounting surface12 of the sleeve member 2 adjacent the mounting surface 12. The capledge 26 comprises a cap contact surface 28 and a cap outer surface 30.

FIGS. 3-9 illustrate a method of manufacturing a sleeve 2 according tosome embodiments. In some embodiments, a block 32 ofethylene-vinyl-acetate (EVA) (FIG. 3 ) is mounted on a support rod 34(FIG. 4 ) to facilitate a grinding process. As shown in FIG. 5 , agrinder 36 shaped to impart a desired configuration is brought intocontact with the block 32 of EVA. As the block 32 makes contact with thegrinder 36, the general shape of the grip component is formed. The samegrinder that forms the mounting surface 12 or body of the sleeve 2 mayalso shape the nipple 14 and/or cap 22 if so included. Alternatively,these portions of the grip G are formed by one or more additionalgrinders of appropriate shape.

In some embodiments, once the shape of the sleeve 2 is completed (FIG. 7), the mounting rod 34 is preferably removed. In some embodiments, themounting rod 34 has an external diameter generally equal to the externaldiameter of the handle portion of an article intended to be insertedinto the sleeve 2. The hole 38 left at the second end 8 can be filledwith an appropriately shaped plug 40. In some embodiments, the plug 40is made from the same material as the sleeve 2 so as to seamlessly orvirtually seamlessly blend in with the sleeve 2. Alternatively, the plug40 may be a different material to facilitate the placement ofaesthetically pleasing designs, or contrasting colors or textures at thesecond end 8 of the sleeve 2. Preferably, in some embodiments, the plug40 includes a small hole 24 or opening to permit the release of air orfluid as described above.

FIGS. 10-12A illustrate a gripping member 50 according to someembodiments. The gripping member 50 is shaped to generally correspondwith the mounting surface 12 of the sleeve 2 when applied thereto. Shownas a panel P, the illustrated embodiment is folded or wrapped around themounting surface 12 to form a substantially vertical seam 52 (FIG. 32 )that joins the side edges 54, 56 of the panel 50 as described in greaterdetail below. Alternatively, the gripping member 50 could be formed as astrip that would in turn be spirally wrapped around the mounting surface12. In some embodiments, multiple panels and/or strips may beincorporated.

FIG. 11 is a section view of the gripping member 50 taken along the line11-11 in FIG. 10 . In some embodiments, the gripping member 50preferably includes an outer layer 58 adhered, bonded, glued orotherwise attached to a base or inner layer 60. The outer layer 58defines an inner surface 62 and an outer surface 64 (FIG. 19 ).Similarly, the inner layer 60 defines an inner surface 66 and an outersurface 68. In some embodiments, a spray on adhesive 70 is applied toone or both of the inner surface 62 of the outer layer 58 and/or theouter surface 68 of the inner layer 60. In some embodiments, the innerlayer 60 comprises EVA to reduce the weight and lower the density of thefinished grip G and to provide a cushioning material that is lessinclined to absorb and hold water or other fluids. This is particularlyuseful in fishing pole applications, for example when the pole isdropped into the water, as the lightweight/low density grip according toembodiments of the present invention will preferably float even whenwet. In some embodiments, the EVA inner layer 60 is betweenapproximately 0.5 and 1.5 millimeters thick. In some embodiments, theEVA inner layer 60 is between approximately 0.75 and 1.25 millimetersthick. In a preferred embodiment, the EVA inner layer 60 isapproximately 1 millimeter thick.

FIG. 12 is an enlarged view of a portion of the gripping member 50designated by the circle 12 in FIG. 11 . As described in greater detailbelow, the outer layer 58 preferably includes a thin non-woven fabriclayer 72 that is saturated with polyurethane 74, by, for example,dipping the thin fabric layer 72 into a polyurethane bath 102. Thepolyurethane 74 is preferably coagulated to form one or more closedcells or pores 76. The non-woven fabric layer 72 has an outer surface 78and an inner surface 80 and may be fabricated of suitable materials suchas nylon, cotton, polyester, or the like and may be felt. The fabriclayer 72 is preferably compressed reduce its thickness prior to theapplication of polyurethane 74 thereto. In some embodiments, thecompression also enhances the rigidity of the fabric layer 72. In someembodiments the compression also spreads the non-woven fibers to enhancethe penetration of the polyurethane 74 into the thin fabric layer 72.Increasing the amount of polyurethane penetration and saturation intothe thin fabric layer reduces the amount of space available for waterand other fluids to soak into and become trapped within the grippingmember. This is particularly useful in fishing pole applications. Insome embodiments, the thin non-woven fabric layer is betweenapproximately 0.1 and 0.5 millimeters. In some embodiments, the thinnon-woven fabric layer 72 is between approximately 0.3 and 0.4millimeters thick. In some embodiments, the thin non-woven fabric layer72 is between approximately 0.3 and 0.35 millimeters thick. In apreferred embodiment, the thin fabric layer 72 is approximately 0.35millimeters thick.

In some embodiments, the thin fabric layer 72 is coated with andsaturated by polyurethane 74. In some embodiments, the polyurethane 74coating the thin fabric layer 72 is between approximately 0.1 and 0.4millimeters thick measured from the outer surface 78 of the fabric layer72. In some embodiments, the polyurethane 74 coating the thin fabriclayer 72 is between approximately 0.15 and 0.25 millimeters thick. In apreferred embodiment, the polyurethane 74 coating the thin fabric layer72 is approximately 0.2 millimeters thick.

Embodiments of the present invention provide a lightweight/low densitygrip with sufficient torsion resistance for use with a variety ofarticles including fishing rods and golf clubs. In some embodiments, afinished gripping member 50 including a combined polyurethane/thinfabric layer 58 adhered to an EVA base layer 60 weighs betweenapproximately 5.0 and 6.0 grams. In a preferred embodiment, the grippingmember 50 weighs approximately 5.3 grams while still providing thesensitive vibration feel and structural benefits to be able to float onwater even when wet.

FIG. 12A is an alternative view of the portion shown in FIG. 12according to some embodiments. In this embodiment, an additional wovenfabric mesh 82 is included in the polyurethane layer 74 during themanufacturing process. In some embodiments, the fabric mesh 82 isattached to the thin non-woven fabric layer 72 prior to dipping in thepolyurethane bath 102. For example, the fabric mesh 82 can be stitchedto an end of the thin fabric layer 72 and the combination dipped into apolyurethane bath 102. An example of the dipping process is described ingreater detail below. The woven fabric mesh 82 generally does not absorbthe polyurethane 74 during the preparation process. In some embodiments,the outer layer 58 of the gripping member 50 includes a saturated thinfabric layer 72 and an un-saturated fabric mesh layer 82. In someembodiments, the fabric mesh 82 includes longitudinally extending fibers(fibers that extend generally along the length of the long axis of agrip or along the long axis of a strip is the finished grip is formedfrom a spirally wrapped strip) and transversely extending fibers. Insome embodiments, the longitudinally extending fibers will preferably beof a larger diameter than the transversely extending fibers. Forexample, the longitudinal fibers may have a diameter betweenapproximately 0.4 and 0.75 millimeters and the transverse fibers mayhave a diameter between approximately 0.25 and 0.5 millimeters. In someembodiments, the longitudinal and transverse fibers may be ofsubstantially equal diameters. The woven fabric mesh 82 may befabricated of suitable materials such as nylon, cotton, polyester, orthe like.

FIGS. 13-24 illustrate a method of manufacturing a gripping member 50according to some embodiments. FIG. 13 is a schematic view of anapparatus 100 useful in some embodiments of the manufacturing method.Generally, in some embodiments, a thin non-woven fabric sheet 72 isdipped into a polyurethane bath 102. In some embodiments, the bath 102is a solution of polyurethane 74 (e.g., polyester, polyether) dissolvedin dimethylformamide (DMF). The solids content of the polyurethane 74will vary in accordance with the desired hardness of such polyurethane74. A preferred solids content solution is approximately 28.5-30.5%,with a viscosity range of about 60,000-90,000 cps measured at 25.+−0.0.5degrees C. The viscosity of the polyurethane bath 102 can be manipulatedto control the thickness of the polyurethane 74 that ultimately collectson the fabric sheet 72. The polyurethane 74 preferably coats both sides78, 80 of the fabric sheet 72 and saturates through the fabric sheet 72.

In some embodiments, not shown, additional liquid polyurethane can beadded to the top surface of the uncoagulated polyurethane 74 that coatsthe thin fabric sheet 72 after the sheet 72 is directed out of thepolyurethane bath 102. The second polyurethane can include one or moredifferent characteristics from the polyurethane 74 in the bath 102 toprovide contrast on the gripping member 50. For example, the secondpolyurethane can include a different color, durometer or level oftackiness.

In some embodiments, the fabric/polyurethane sheet is directed out ofthe polyurethane bath 102 and into a first processing stage 104 in whicha portion of the polyurethane 74 is removed from the bottom 80 of thefabric sheet 72. In some embodiments, a majority of the polyurethane 74is removed. In addition, the top surface 86 of the polyurethane 74 ispreferably smoothed. In some embodiments, the processing stage 104occurs in a compression system comprising a pair of rollers 106, 108.The spacing of the rollers 106, 108 can be used to help determine thethickness of the polyurethane 74 coating the fabric sheet 72. In someembodiments, the bottom roller 108 includes a rubber surface 110 or asurface comprising another similar resilient material. The bottom roller108 preferably removes a portion of the polyurethane 74 and in someembodiments the majority of the polyurethane 74 from the bottom 80 ofthe fabric sheet 72. In some embodiments, the bottom roller 108 can besubstituted with any other similar apparatus which strips offpolyurethane 74 from the bottom of the fabric sheet 72. For example, anon-rotating edge may be used. In some embodiments, the top roller 106includes a stainless steel surface 112 or a surface comprising anothersimilar smooth, hard surface. The top roller 106 preferably smoothes thetop surface 86 of the polyurethane 74 that coats the fabric sheet 72.

When a wet coagulation process is used, the saturated and coated fabricsheet 58 is then preferably directed into one or more water baths 120 todisplace the DMF from the polyurethane 74 and to facilitate theformation of pores 76 in the polyurethane 74. From the water bath 120,the coagulated polyurethane sheet 58 is preferably directed to anotherprocessing stage 114 to press water and DMF from the coagulatedpolyurethane sheet 58.

In some embodiments, the EVA sleeve 2 is injection molded rather thanground down from a block of EVA foam. Ethylene vinyl acetate copolymerspossess many excellent characteristics such as low weight, low density,flexibility, transparency, non-toxicity and good resistance toenvironmental stress cracking, etc. Some embodiments of the presentinvention overcome the difficulties of working with injection moldedEVA. For example, EVA coagulation is a relatively slow process. Afterinjection molding a rough EVA sleeve, a core bar can be inserted insidethe sleeve 2 and the sleeve 2 can be transferred to an appropriate moldto control the shape of the finished product. Controlling temperatureand time facilitates effective control of the EVA coagulation. In someembodiments, the density of the EVA included in the sleeve is less thanapproximately 1 g/cm³. In some embodiments, the density is betweenapproximately 0.9 and 1 g/cm³. In a preferred embodiment, the density isbetween approximately 0.930 and 0.943 g/cm³. Controlling the degree ofcoagulation of the EVA allows embodiments of the invention to include anEVA sleeve whose volume is, for example, approximately doubled ortripled from the original volume. Therefore, in some embodiments, thedensity of the finished sleeve 2 can be approximately one half or onethird of the original density.

In theillustrated embodiment, the length of the threaded portion 1052 isapproximately 6 cm. However, the threaded portion 1052 can range fromapproximately 1 cm to approximately 10 cm.

The threaded adapter 1050 is preferably made of a rigid material that isfavorable for thread formation. For example, the threaded adapter 1050can be made of a metal, composite, or rigid plastic, such as aluminum,Delrin®, or polyethylene. In other embodiments, the threaded adapter1050 can be made of any other material having sufficient strength towithstand the forces experienced by the handle 1020.

The threaded adapter 1050 and tubular shaft 1040 can be coupled by anymeans, such as those described above for the coupling of the gripportion 1030 and tubular shaft 1040. For example, the coupling means caninclude adhesives, threaded connections, or set screws. In someembodiments, the threaded adapter 1050 can be made as a unitary piecewith the tubular shaft 1040. The threaded adapter 1050 and the tubularshaft 1040 can be machined or molded into a single piece.

In some embodiments, the threaded adapter 1050 can be a hollow sleevewith outer threads configured to fit around the outer surface 1046 ofthe tubular shaft 1040. In these embodiments, the tubular shaft 1040 canhave a reduced outer diameter along the second portion 1044 where thehollow threaded adapter 1050 is positioned to account for the additionaldiameter from the hollow threaded adapter 1050.

FIGS. 54 and 55 illustrate an embodiment of an assembled handle 1020.The tubular shaft 1040 can be inserted into the grip portion 1030 andsecured together through any of the means described above. In someembodiments, for example when adhesives are incorporated, the outersurface 1046 of the tubular shaft 1040 and/or the grip cavity 1038 ofthe grip portion 1030 can be provided with a lubricant to assistassembly. Preferably, the lubricant will dry or will otherwise lose itslubricity after time for a more secure fit.

In the illustrated embodiment, the tubular shaft 1040 is inserted intogenerally the entire length of the grip portion 1030. In someembodiments, the length of the tubular shaft 1040 is greater than thelength of the grip portion 1030, resulting in a portion of the tubularshaft 1040 extending outside of the grip cavity 1038, as illustrated inFIGS. 54 and 55 . Though shown extending beyond the grip cavity 1038, insome embodiments the tubular shaft 1040 and the grip cavity 1038 can becommensurate or approximately equal in length. In some embodiments thegrip cavity 1038 can extend beyond the tubular shaft 1040. In theillustrated embodiment, the tubular shaft 1040 extends about 6 cmoutside of the grip cavity 1038. In other embodiments, the tubular shaft1040 may extend less or more than 6 cm outside of the grip cavity 1038.As described above, in some embodiments, the tubular shaft 40 may notextend outside of the grip cavity 1038. In some embodiments, the tubularshaft 1040 can be shorter in length than the length of the grip portion1030. However, the tubular shaft 1040 can be inserted only partiallyinto the length of the grip portion 1030, wherein a portion of thetubular shaft 1040 still extends outside of the grip cavity 1038.

With continued reference to FIGS. 54 and 55 , the threaded adapter 1050can be inserted into the second portion 1044 of the tubular shaft 1040and coupled together by any of the means described above. In theillustrated embodiment, the threaded adapter 1050 is inserted about 6 cminto the tubular shaft 1040. In other embodiments, the threaded adapter1050 can be inserted more or less than 6 cm into the tubular shaft 1040.

With reference to FIGS. 52 and 56 , the rod portion 1060 can include aconnector portion 1062 having a connector cavity 1064. The connectorcavity 1064 can have features complimentary to the assembled handle 1020for releasably securing the handle to the rod portion 1060. In theillustrated embodiment, the connector cavity 1064 is an elongateaperture with inner threads disposed along the distal portion 1066 ofthe connector cavity 1064 that are complimentary to the outer threads onthe handle 1020. The rod portion 1060 can also comprise a depression1070 at the proximal end 1068 of the connector cavity 1064 that isconfigured to mate with the nipple 1033 on the grip portion 1030.

As illustrated in FIG. 57 , the tubular shaft 1040 and the threadedadapter 50 of the handle 1020 can be inserted into the connector cavity1064 until the outer threads on the handle 1020 engage the inner threadsin the connector cavity 1064. As the connection is tightened, the handle1020 is drawn toward the rod portion 1060. Preferably, the threadedportion 1052 of the threaded adapter 1050 is longer than the length ofthe inner threads of the connector cavity 1064 so that the handle can beinserted sufficiently into the rod portion 1060 to form a tight junctionbetween the depression 1070 and the nipple 1033, as illustrated in FIG.57 . In some embodiments, the tubular shaft 1040 can mate with the innerwalls of the connector cavity through a interference or tight fit toprovide additional rigidity to the assembly.

Although described with reference to a threaded connection between thehandle 1020 and rod portion 1060, other connection means are alsocontemplated. In alternate embodiments, the coupling between the handle1020 and the rod portion 1060 can include any connection means thatprovides a rigid, yet releasable attachment. For example, the couplingcan include latches, hooks, or quarter-turn connections.
